[Qemu-devel] [PATCH 0/4] backup: fix skipping unallocated clusters

[Vladimir Sementsov-Ogievskiy]

Hi all!

There is a bug in not yet merged patch
"block/backup: teach TOP to never copy unallocated regions"
in https://github.com/jnsnow/qemu bitmaps. 04 fixes it. So, I propose
to put 01-03 somewhere before
"block/backup: teach TOP to never copy unallocated regions"
and squash 04 into "block/backup: teach TOP to never copy unallocated regions"

Based-on: https://github.com/jnsnow/qemu bitmaps

Vladimir Sementsov-Ogievskiy (4):
  block/dirty-bitmap: switch _next_dirty_area and _next_zero to int64_t
  block/dirty-bitmap: add _next_dirty API
  block/backup: use bdrv_dirty_bitmap_next_dirty
  block/backup: fix and improve skipping unallocated in backup_do_cow
